Full composite material ball cage bridge plugs
It is mainly used in the oil, gas and water layer for temporary or permanent block, concrete can fit for the production of shaft seal, water plugging and fracturing, acidification, testing etc construction. Conditions.
Structure: Composed of top joint, center pipe, rubber tube, top slip /bottom slip, top vertebral body /bottom vertebral body, top protect bowl / bottom protect bowl, the release pin, pumping ring and block bolts and other parts.
Technical parameters for reference:
This kind of bridge plug are finished with epoxy resin & glass fiber and carbon fiber composite material.
Density of 1.85 g/cm3.
Easy to drill down
Slips with composite material base seat + metal slip granule or ceramic slip granule
(slip grain diameter is 10 mm, height is 8 mm. It can be directly ruled out when drilling)
The bridge plug for casing with diameter 5.5 inch, inner diameter 121 ~ 124 mm.
Bridge plug length is 710 mm,
Outside diameter is 710 mm, inner diameter is 30 mm, weight 9.5 KG.
The bridge plug meets downhole fracturing requirements:
Bearing pressure 70 MPa
Resistant temperature: 150 ° C
Sitting seal force; 24 tons
The bridge plug drilling and grinding time about 30 minutes (the specific time according to well conditions is slightly different. Concave grinding shoes are recommended ).
The bridge plug with diameter of 38.1 mm composite ball sealer (also available with ball cage type bridge plug- place the fracturing ball in the bridge plug in advance, press it directly after setting, reduce the pitching process after setting).
The three piece packing elements and metal back-up ring combine for a superior seal system.
Compact, running easily.
The bridge plug can be directly set on WST wireline setting tool or HSB hydraulic setting tool.
Composite material for easy drillability.
Light weight debris for easy flowback
